Enigma - 1

OK..I've spent so long deliberating and fussing, I'm just going to get on with this...I've started with the eyes as usual and radiated out from there.It's important to achieve the right balance of contrast early on as it will affect the rest of the drawing...also to establish which areas of the subject will have the most light...currently the subject is surrounded by plain paper, but eventually I'll want the right side of the face to be the brightest...so a very careful omission of dots is needed to achieve the desired effect.
